タラッソクヌス (Thalassocnus ) は中新世から鮮新世にかけて南アメリカ大陸太平洋岸に生息していた半水生の地上性オオナマケモノの絶滅属。本属のみでタラッソクヌス亜科 (Thalassocninae) を形成する単型である。属している5種（T. antiquus、T. natans、T. littoralis、T. carolomartini、T. yuacensis ）は時間種 (Chronospecies) の典型であり、同じ一つの系統の中で徐々に海洋生活に適応してきたグループである。水生のオオナマケモノとしては知られている限り唯一のものであり、ペルーの Pisco累層、チリの Bahía Inglesa累層、Coquimbo累層、Horcón累層から発見されている。タラッソクヌス亜科 (Thalassocninae) はメガテリウム科 (Megatheriidae) の亜科とされた[2]こともノスロテリウム科 (Nothrotheriidae) の亜科とされた[3]こともある。
